Technical details. The best available source (S-VHS) was made into a digital master at 768 x 576 pixels and 4:2:2 chroma subsampling. These files, when played onto a good monitor will appear better than they did when played off a 1990 domestic VHS machine onto a typical 1990 domestic CRT screen. However, the files are very large (about 30GB per hour) and to facilitate streaming, a 576p compressed mp4 version at 50% quality is provided here (about 800MB per hour) and there will be some visible artifacts.

Camera: John Turner. Digitisation & Editing: Robin Marshall.
